description="
An alternate POSIX capabilities library.
  	
The libcap-ng library is intended to make programming with POSIX
capabilities much easier than the traditional libcap library.

It includes utilities that can analyse all currently running
applications and print out any capabilities and whether or not it has
an open ended bounding set. An open bounding set without the securebits
\"NOROOT\" flag will allow full capabilities escalation for apps
retaining UID 0 simply by calling execve.
